Dave Jiang da435aedb0 dmaengine: idxd: fix array index when int_handles are being used 
The index to the irq vector should be local and has no relation to
the assigned interrupt handle. Assign the MSIX interrupt index that is
programmed for the descriptor. The interrupt handle only matters when it
comes to hardware descriptor programming.

Fixes: eb15e7154f ("dmaengine: idxd: add interrupt handle request and release support")
